    On a serious note:

    I think beenthere creates accounts to either
    A: get people to give out DIY advice.
    B: Get people to be beligerant.

    Either way, he gets to hand out points.

    There is no way any person could honestly believe they can DIY a furnace, and not even know you need to PVC vent a 90% furnace.

    How many times must one fix something before it is fixed?

    One question though, if I am doing a PVC pipe for vent and intake, how many ups and dips and right and left turns are allowed before the vent reaches the hole in the wall and then comes out to vent. Seems one cannot vent a furnace to the front of the house in my condo, only back of the house is allowed. Hence the zig zags and ups + downs in the venting route until the final exit from wall is attained.

    By the way, my plans were never to DIY the furnace installation. I just wanted to do the 80-90% of the work so that when I call HVAC pro, then I can hopefully avoid majority of the charges, pretty much leaving the Pro to connect last 2-3 wires and get the furnace going.

    Which makes it a 80 to 90% DIY install.

    I just needed this or such information to take right decisions. Hence, HE furnace should have PVC gas and water tight pipes only and they should not share the vent with any other gas appliance. Thanks all for the inputs.
    Thats not why you vent horizontally. A HE furnace can vent in either direction.

    A HE Furance is not intended to be common vented into a galvanized natural draft flue. The ID fan on it si intended for a dedicated exhaust vent. It has enough force to push the air back out the hot water heater, or at least cause the water heater to back draft. You cannon common vent HE or power vent appliances because hte fane would fight each other and cause too much back pressure and again potentially back venting into the home. Additonally, HE furnaces have lower flue temperatures, which means the water vapor in the flue gases is condensing, and that condensation is acidic, so it will eat away at galvanized pipe.

    IF your not goign ot hire a pro, at least find an installation manual online and read it. IT will tell you the minimum basics of a safe installation. Sadly, some less skilled pros out there could use to read the manuals too.

    GAS APPLIANCES ARE DANGEROUS! venting that improperly can kill you and your family by carbon monoxide, carbon dioxide, and the risk of fire.

    Now for my soap box... Personally, I think natural draft appliances for hte most part should go away. I know that can be installed safely, but there's just too much potential for problems IMO. Direct vent or power vent is the only way to go IMO.

    There is a thread on here where a HO DIYed the gas line into his new furnace, turned it on and luckily went out to dinner. The photos are amazing, the furnace sat in the basement on one end and you can see the siding buckled about half way down the house. I hope someone can find this tread, maybe it will knock some sense into this guy.

    If you live in a condo, you might want to let your neighboors know what your doing.

    With your wide experience in accounting, they might be wary of you installing your own equitment, since you'll kill them too.
